Patent JP-2005510134-A (JP)
IPC: H04B3/46
Filed: 2001-11-16
Abstract: Method and device for classifying network connections based on geographical coordinates of a transmitter and a receiver of a network connection to be classified. By a calculating unit, one or more distance factors are determined, the distance factors indicating actual network connection length according to air distance. An attenuation distribution factor is determined based on known data of network connections, indicating the ratio of attenuation of different partial connection elements of a network connection in relation to one another. Further, data transfer margins are determined to calculate maximum data throughput rates for different modem types. Based on the actual connection length, the attenuation distribution factor, and the data transfer margin, the network connection is classified, according to its maximum throughput rate, by the calculating unit. In particular, the method can be applied to networks based on copper-wire connections, for example the last mile in telephone networks.
